EXTENSION-TABLE.

Specification of Lettrs'atent.

Patented Dec. 16, '1919.

Application led August 5, 1919. Serial'No. 315,414.

To all whom it may concern:

Be it known that I, HERMAN H. WLELAGE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented newv and useful Improvements in Extension-Tables, of which the following is a specification.

This invention relates to furniture, particularly to extension tables, and .has for. it's object the provision of a table comprising va rigid support upon which are slida ly mounted main leaves beneath which under ordinary conditions are disposed the auxiliary leaves whereby the auxiliary kleaves -will be normally concealed from view whileyet remaining in yposition ready for instant use,

.means being .provided whereby upon outward movement of the main leaves, the auxiliary leaves may be moved'upwardly to be disposed and supported between ,the main leaves whereby to serve as a continuation thereof with the entire top surface of the table lying in one plane.

An important object is the provision of .a table of this character which is provided-,at each end with readily operable means whereby an auxiliary leaf may be elevated into position between the main f leaves, whereby the degree of extension of the table may be regulated to suit the requirements Vof various occasions.

Another object is the provision of a table of this character in whichthe construction is such that when an auxiliary leaf is .elevated and disposed between the main leaves the auxiliary leaf will be retained in elevated position without Vany necessity for theV employment of additional securing means.

An additional object is the provision of a table of this character which will be simple and inexpensive'in manufacture, which Vmay be quickly and easily enlarged when desired, which may .be operated with the minimum expenditure of time and labor, which will be durable in service, and a general improvement in theart.

With the above and other objects and advantages in view, the invention .consists in the details of construction to be hereinafter more fully described and claimed, vand illustrated in the accompanyingdrawings, in whichv Figure 1 is a top plan view ofthe table `in normal position, part of the table 'top' being broken away.

F ig. 2 is a bottom plan view of the same,

3 is a longitudinal sectional view, ,that lis the section is taken transversely of the main and auxiliary leaves, on the line of Fig. 1, Fig. Lis a sectional view taken on the line .4.,L1,of Fig. l.

l5 is'a crosssectional view taken on theiline 5 5 of Fig. 2,

ig, 6 -is atop plan view of a table ,in extended position, with auxiliary leaves exposed and lshowingone removed whereby to disclose the structure therebeneath, in such position that the leaf vwould bein its lowermostY position.

Fig. 7 visa similarview showing theparts arranged; in the position they assume when the lauxiliary ,leaf is elevated,

Erg.'8 1sa'long1tud1nal sectional view on A)portions theside rails 15 are `provided with out out portlons 18. Disposed upon the rectangular frame thus formed, are the main leaves 19 ,and 20, each of whichis provided onr its'underside with cleats 21 slidably engaging against the sides lof ,the rails 15 whereby 'these leaves will be slidably mounted upon the top of the frame. Also secured upon 'theV underside of the leaves 19 andV 20,

` are pins 22 adapted for engagement with the end rails 16 for limiting outward movement of the' leaves-away from each other .so that when they yare moved outwardly as 'far as possible vtheir inner edges will register with the ends .of the cut out portions 18 in the side rails.

Secured upon the rectangular frame immediately beneath the cut out portions 18 are transverse boards 23 and 24 which are identical in construction and with which are associated auxiliary leaves 25 and 26 which are normally disposed within the cut out portions 18 but which may be elevated to be l.disposed between Vthe main leaves 19 and`20, with Vftheir upper surfaces lying in the same plane with the upper surfaces of the main leaves. Each board or 2e has disposed upon the center of its top a member 27 having bifurcarted ends 28 and secured upon the squared upper extremity 29 of a lever which is right angular in shape, which extends through the center of the board and which has an arm 30 extending horizontally toward the adjacent end rail i6. Also secured upon the top of each board are pairs of brackets 3l within which are slidably disposed bars 32 having angular inner ends 33 pivotally connected with links 3i which are in turn pivotally connected within the -bifurcations 23 in the member 27. Pivotally connected with the outer ends of the bars are links 35 which are pivotally connected with angular arms 36 formed on U-shaped yokes 37 pivoted upon the underside of each leaf 19 and 20. Also secured upon the underside Aof each leaf 19 and 20, are flange members 3S which engage against the inner sides of the side rails 15.

Secured upon the underside of each leaf 25 or 26 are guide brackets 39 within which are slidably mounted transversely disposed rods 4l() having down-turned ends 41. Each rod e() carries at its center a fork 42 which straddlingly engages the lever arm 30 on the associated board.

rl`he normal position of the table is shown in Fig. 1. hen the table is in this position, the main leaves 19 and 20 have their inner edges contacting and the leaves 25 and 26 are disposed within the out out portions 18 in the side rails and are entirely concealed from view while remaining in position for instant use when desired. Then it is desired to enlarge the table, it is first necessary that a leaf 19 or 20 be slid outwardly upon the rectangular supporting frame so as to be disposed in non-obstructing relation to the leaf 25 or 26 disposed normally therebeneath. At this time the rod 40, fork Ll2, lever arm 20, and member 27 are in such position that the yokes 37 will have their inner ends drawn toward each other, as clearly shown in the drawings. In order to elevate the leaf 25 or 26, as the case may be, it is merely necessary that the operator grasp either of the down-turned ends Ll1 of the proper rod 4() and slide the rod 40 laterally within its guide brackets 39, whereupon the fork 42 carried by the rod will move the lever 30 and consequently the member 27 so that the links 34e and 35 will cause the yokes 37 to be swung downwardly into engagement with the top of the associated board which will result in elevation of the auxiliary leaf into the space between the main leaves 19 and 20. Vihen this swinging movement of the yokes 37 o teurs, the yokes are swung somewhat beyond center so that subsequent accidental depression of the auxiliary leaf will be prevented. In case it is desired to enlarge the table still more, both of the main leaves 19 and 20 are pulled apart so that both of the auxiliary leaves 25 and 26 may be elevated, the operation of elevating both of the auxiliary leaves being` the saine. l/Vhen it is desired to restore the table to its original position and condition, it is merely necessary that the operator grasp the down-turned end 41 of the rod Ll0 associated with the leaf which is elevated, and move the rod laterally whereby to move the member 27 and its associated links for pulling the yokes 37 toward each other which will result in permitting the leaf 25 or 26 to return to its normal position within the cut out portions 18. From the foregoing description and a study of the drawings it will be apparent that l have thus provided a simply constructed table which will be very quickly and easily adjusted so that the size of the table may be varied by the interposition of auxiliary leaves between the main leaves, the auxiliary leaves being normally out of sight beneath the main leaves but yet in position ready for instant use. y

lhile l have shown and' described the preferred embodiment of my invention it is of course to be understood that I reserve the right to make such changes in the form, construction, and arrangement of parts as will not depart from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention, I claimz- 1. An extension table comprising a leg supported rectangular frame provided in the upper edges of its siderails with cut out portions, a pair of main leaves slidably mounted 'upon said frame and normally covering said cut out portions, auxiliary leaves extending transversely of said frame and having their end portions normally seating within said cut out portions, boards secured transversely of said frame beneath and in spaced relation to said auxiliary leaves, a pair of yokes pivoted upon each board and normally lying Hat thereon, said yokes being connected with said auxiliary leaves, and means for swinging said yokes outwardly and toward each other whereby to elevate the auxiliary leaf associated therewith subsequent to the separation of said main leaves.

2. An extension table comprising a leg supported rectangular frame provided in the upper edges of its side rails with cut out portions, a pair of main leaves slidably mounted upon said frame and normally covering said cut out portions, auxiliary leaves extending transversely of said frame and having their end portions seating within said cut out portions, a board extending transversely of said frame beneath and in lli spaced relation to each auxiliary leaf, a member pivoted upon each board, a lever arm connected With said member and extending beneath the associated board7 yokes pivoted upon the underside ot' the associated auxiliary leaf, and links connected With said yoke and said member whereby upon move ment or' said lever arm said yokes Will be swung into engagement With the top of the board for elevating the auxiliary leaf subsequent to separation of said main leaves.

An extension table comprising a leg supported rectangular frame provided in its side rails With cut out portions, main leaves slidably mounted upon the top of said .trame and normally covering said cut out portions, auxiliary leaves extending transversely of said frame With their end portions resting Within said cutJ out portions, a board extending transversely of the frame beneath each auxiliary leaf, guide brackets secured upon each board, a rod slidable through said brackets and having downturned ends, a fork carried by each rod, a member mounted for pivotal movement upon the upper surface of each board, a lever arm secured to said member and engaging Within the adjacent fork, a pair ot yokes pivoted upon the underside of each auxiliary leaf, bars mounted for slidable movement on the upper surface of each board at opposite sides of said member, links connecting the inner ends of said bars with said bar, and

links pivotally connectin the outer ends of said bars with said yokes whereby upon movement of Said rod in one direction engagement of said fork with said lever arm Willresult in movement of said member for causing outward movement of said bars to swing said yokes outwardly to elevate the associated auxiliary leaf.

In testimony whereof I affix my signature.v
